BACKGROUND OF THE INVENTION A. Field of the Invention

The present invention relates generally to the fields of cosmetics. In particular, the invention concerns topical skin compositions that can include a combination of Hylocereus undatus fruit extract and Aloe barbadensis leaf extract to reduce TNF-α expression and reduce oxidative damage caused by free radicals (anti-oxidative properties) in skin.

B. Description of Related Art

Many factors contribute to skin aging and the appearance of aging such as the actual age of a person, the amount of exposure to environmental factors (e.g., sun light, pollution, chemicals, smoke, etc.), and how well a person has taken care of their skin. In particular, skin aging concerns two processes—intrinsic aging, which is related to the natural aging process and genetic influences, and extrinsic aging, which is accumulated damage due to environmental factors such as exposure to chemicals and UV rays and loss of moisture.

Intrinsic aging process in cells and skin can be related to the loss of proper function of the skin in maintaining biochemical pathways. Such pathways can control the oxidative/reductive environment balance in the skin, the regulation of inflammation, and the maintenance of the moisture balance of the skin. Losses of proper function of the skin can lead to increased oxidative damage, increased inflammation, dry skin, loss of skin firmness, increased skin unevenness, and increased fine lines and wrinkles.

Exposure to oxidative chemicals, exposure to UV rays, and intrinsic aging can lead to the accumulation of oxidative stress through free radical formation. Oxidative stress can damage skin proteins, lipids, and DNA. This damage leads to skin aging, which includes loss of elasticity, loss of dermal proteins, lines and wrinkles, and abnormal pigmentation.

Exposure to some chemicals, exposure to UV rays, and intrinsic aging can also cause inflammation. Inflammation can occur through inflammatory cytokines such as TNF-α. As inflammation persists, enzymes such as matrix metalloproteinases are involved in the breakdown of dermal proteins, which allows immune cells to migrate. This breakdown in dermal proteins such as laminin, elastin, and collagen can lead to skin aging.

UV rays, through sun exposure or the use of ultraviolet lamps (for example, tanning beds), can induce genetic mutations that leads to skin damage. Further, exposure to UV rays can induce production of melanin. When exposed to UV rays, the keratinocyte (outermost cell of the skin) releases signaling molecules, such as α-melanocyte-stimulating hormone (α-MSH), and inflammatory cytokines. These hormones trigger melanocytes to produce melanin (melanogenesis). The production of melanin can result in variations in the color of the skin. For example, a person's skin can have a sallow tone or hyperpigmented spots. Conventional depigmenting agents, such as hydroquinone, corticosteroids, and kojic acid can raise several safety concerns (for example, ochronosis, atrophy, carcinogenesis, and other local or systemic side effects) with long-term exposure.

Extrinsic and intrinsic factors can also reduce the moisture in skin. Exposure to chemicals, solvents, washing, cosmetics, fabrics, or dry environments are some of the many ways that skin can lose moisture. Loss of moisture can lead to breaks or fine lines and wrinkles in the skin. Maintaining moisture of the skin and/or hair helps overcome some unwanted changes in skin and hair. However, maintaining moisture of the skin can be difficult in the daily exposure to harsh extrinsic factors. Moisturizers have been designed to attempt to remedy such difficulties. Moisturizers for the skin and hair are complex mixtures of chemical agents specially designed to make the external layers of the skin (epidermis) softer and more pliable. They increase the skin's hydration (water content) by reducing evaporation. Naturally occurring skin lipids and sterols, as well as artificial or natural oils, humectants, emollients, lubricants, etc., may be part of the composition of commercial skin moisturizers. They usually are available as commercial products for cosmetic and therapeutic uses, but can also be made at home using common pharmacy ingredients. However, moisturizers are not perfect. Some problems associated with moisturizers include unpleasant tactile properties (e.g., heavy, greasy, or sticky feel), instability, skin-irritation, or insufficient moisturization capabilities.

The combination of intrinsic and extrinsic factors eventually leads to visible signs of aging. Current products on the market either do not effectively address the signs or causes of ageing or the effects of extrinsic factors on the skin and/or they have skin irritating effects. For example, current products may not adequately address skin inflammation and oxidative damage caused by free radicals.

SUMMARY OF THE INVENTION

The inventors have identified a solution to the aforementioned problems of sufficiently addressing skin inflammation and oxidative damage caused by free radicals. The solution resides in a combination of Hylocereus undatus fruit extract (dragon fruit extract) and Aloe barbadensis leaf extract that can effectively provide antioxidative properties and inhibit skin inflammation at the same time. This combination of ingredients can be incorporated into a wide variety of products such as skin exfoliating products, skin moisturizers, sunscreens, and skin cleansers and toners. In some instances, this combination of ingredients can be incorporated into a wide variety of formulations such as emulsions, solutions, serums, anhydrous bases, and/or gels. Notably, the combination of extracts are chemically compatible with one another and maintain their anti-oxidative and TNF-α inhibition properties. As shown in non-limiting Example 1, Aloe barbadensis leaf extract inhibits TNF-α and provides antioxidant benefits. Hylocereus undatus fruit extract provides antioxidant benefits, but was not found to inhibit TNF-α. Further, the combination of Hylocereus undatus fruit extract and Aloe barbadensis leaf extract provide antioxidant properties and inhibit TNF-α expression.

A. Example 1 (Skin Benefits of Active Ingredients)

The efficacy of the ingredients were determined by the following methods.

It was determined that Hylocereus undatus fruit extract provides antioxidant benefits. It was also determined that Aloe barbadensis leaf extract inhibits TNF-α and provides antioxidant benefits. It was also determined that the combination of Hylocereus undatus fruit extract and Aloe barbadensis leaf extract provide antioxidant properties and inhibit TNF-α expression. A summary of quantitative results is found in Table 1 and the methods used to determine the properties of the ingredients are provided below.

TABLE 1 Assay Ingredient Activity Inhibition of 1% Aloe barbadensis leaf extract −72% TNF-α 1% Hylocereus undatus fruit extract No inhibition 2% Hylocereus undatus fruit extract −79.4%  and 1% Aloe barbadensis leaf extract Antioxidant 1% Aloe barbadensis leaf extract −39% Capacity 1% Hylocereus undatus fruit extract −36.08%   2% Hylocereus undatus fruit extract −65% 2% Hylocereus undatus fruit extract −97.86%   and 1% Aloe barbadensis leaf extract

Tumor Necrosis Factor Alpha (TNF-α) Assay: The prototype ligand of the TNF superfamily, TNF-α, is a pleiotropic cytokine that plays a central role in inflammation. Increase in its expression is associated with an up regulation in pro-inflammatory activity. A bioassay was used to analyze the effect of Hylocereus undatus fruit extract, Aloe barbadensis leaf extract, and a combination of the two ingredients on the production of TNF-α by human epidermal keratinocytes. The endpoint of this assay was a spectrophotometric measurement that reflected the presence of TNF-α and cellular viability. It was determined that Aloe barbadensis leaf extract and a combination of Aloe barbadensis leaf extract and Hylocereus undatus fruit extract inhibit TNF-α production at −72% and −79.4%, respectively.

Subconfluent normal human adult keratinocytes (Cascade Biologics) cultivated in EpiLife standard growth medium (Cascade Biologics) at 37° C. in 5% CO₂, were treated with phorbol 12-myristate 13-acetate (PMA, 10 ng/ml, Sigma Chemical, #P1585-1MG) and the test ingredients and combination thereof for 6 hours. PMA causes a dramatic increase in TNF-α secretion which peaks at 6 hours after treatment. Following incubation, cell culture medium was collected and the amount of TNF-α secretion quantified using the sandwich enzyme linked immuno-sorbant assay (ELISA) from R&D Systems (#DTA00C) described below.

The quantification assay employed the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for TNF-α had been pre-coated onto a microplate. Standards and samples were pipetted into the microplate wells and TNF-α was bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for TNF-α was added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution was added to the wells and color developed in proportion to the amount of TNF-α bound in the initial step. A microplate reader was used for detection at 450 nm. The color development was stopped so that the intensity of the color could be measured.

Antioxidant (AO) Assay: The antioxidant system of living organisms includes enzymes such as superoxide dismutase, catalase, and glutathione peroxidase; macromolecules such as albumin, ceruloplasmin, and ferritin; and an array of small molecules, including ascorbic acid, α-tocopherol, β-carotene, reduced glutathione, uric acid, and bilirubin. The sum of endogenous and food-derived antioxidants represents the total antioxidant activity of the extracellular fluid. Cooperation of all the different antioxidants provides greater protection against attack by reactive oxygen or nitrogen radicals, than any single compound alone. Thus, the overall antioxidant capacity may give more relevant biological information compared to that obtained by the measurement of individual components, as it considers the cumulative effect of all antioxidants present in plasma and body fluids.

An in vitro bioassay was used to measure the total anti-oxidant capacity of Hylocereus undatus fruit extract, Aloe barbadensis leaf extract, and a combination of the two ingredients. It was determined that Aloe barbadensis leaf extract, Hylocereus undatus fruit extract, and a combination of Aloe barbadensis leaf extract and Hylocereus undatus fruit extract possess antioxidant capacities. Specifically, the extracts possess antioxidant capacities compared to Trolox of −39% for a 1% Aloe barbadensis leaf extract solution, −36.08% for a 1% Hylocereus undatus fruit extract, −65% for a 2% Hylocereus undatus fruit extract, and −97.86% for a 2% Hylocereus undatus fruit extract and 1% Aloe barbadensis leaf extract solution.

The assay relied on the ability of antioxidants in the sample to inhibit the oxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®+ by metmyoglobin. The capacity of the tested ingredients in the sample to prevent ABTS oxidation was compared with that of Trolox, a water-soluble tocopherol analogue, and was quantified as molar Trolox equivalents. Anti-Oxidant capacity kit #709001 from Cayman Chemical (Ann Arbor, Mich. USA) was used as an in vitro bioassay to measure the total anti-oxidant capacity of each of the tested ingredients. The protocol was followed according to manufacturer recommendations.

D. Example 4 (Additional Assays)

Assays that can be used to determine the efficacy of any one of the ingredients or any combination of ingredients or compositions having said combination of ingredients disclosed throughout the specification and claims can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures.

B16 Pigmentation Assay: Melanogenesis is the process by which melanocytes produce melanin, a naturally produced pigment that imparts color to skin, hair, and eyes. Inhibiting melanogenesis is beneficial to prevent skin darkening and lighten dark spots associated with aging. This bioassay utilizes B16-F1 melanocytes (ATCC), an immortalized mouse melanoma cell line, to analyze the effect of compounds on melanogenesis. The endpoint of this assay is a spectrophotometric measurement of melanin production and cellular viability. B16-F1 melanocytes, can be cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO₂ and then treated with any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification for 6 days. Following incubation, melanin secretion is measured by absorbance at 405 nm and cellular viability is quantified.

Collagen Stimulation Assay: Collagen is an extracellular matrix protein critical for skin structure. Increased synthesis of collagen helps improve skin firmness and elasticity. This bioassay can be used to examine the effect of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification on the production of procollagen peptide (a precursor to collagen) by human epidermal fibroblasts. The endpoint of this assay is a spectrophotometric measurement that reflects the presence of procollagen peptide and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for procollagen peptide has been pre-coated onto a microplate. Standards and samples can be pipetted into the wells and any procollagen peptide present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for procollagen peptide can be added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution can be added to the wells and color develops in proportion to the amount of procollagen peptide bound in the initial step using a microplate reader for detection at 450 nm. The color development can be stopped and the intensity of the color can be measured. For generation of samples and controls, subconfluent normal human adult epidermal fibroblasts (Cascade Biologics) cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO₂, can be treated with each of the combination of ingredients or compositions having said combinations disclosed in the specification for 3 days. Following incubation, cell culture medium can be collected and the amount of procollagen peptide secretion quantified using a sandwich enzyme linked immuno-sorbant assay (ELISA) from Takara (#MK 101).

Elastin Stimulation Assay: Elastin is a connective tissue protein that helps skin resume shape after stretching or contracting. Elastin is also an important load-bearing protein used in places where mechanical energy is required to be stored. Elastin is made by linking many soluble tropoelastin protein molecules, in a reaction catalyzed by lysyl oxidase. Elastin secretion and elastin fibers can be monitored in cultured human fibroblasts by staining of cultured human fibroblasts using immunofluorescent antibodies directed against elastin.

Laminin and Fibronectin Stimulation Assay: Laminin and fibronectin are major proteins in the dermal-epidermal junction (DEJ) (also referred to as the basement membrane). The DEJ is located between the dermis and the epidermis interlocks forming fingerlike projections called rete ridges. The cells of the epidermis receive their nutrients from the blood vessels in the dermis. The rete ridges increase the surface area of the epidermis that is exposed to these blood vessels and the needed nutrients. The DEJ provides adhesion of the two tissue compartments and governs the structural integrity of the skin. Laminin and fibronectin are two structural glycoproteins located in the DEJ. Considered the glue that holds the cells together, laminin and fibronectin are secreted by dermal fibroblasts to help facilitate intra- and inter-cellular adhesion of the epidermal calls to the DEJ. Laminin and fibronectin secretion can be monitored by quantifying laminin and fibronectin in cell supernatants of cultured human fibroblasts treated for 3 days with culture medium with or without 1.0% final concentration of the test ingredient(s). Following incubation, laminin and fibronectin content can be measured using immunofluorescent antibodies directed against each protein in an enzyme linked immuno-sorbant assay (ELISA). Measurements are normalized for cellular metabolic activity, as determined by bioconversion of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS).

ORAC Assay: Oxygen Radical Absorption (or Absorbance) Capacity (ORAC) of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification can also be assayed by measuring the antioxidant activity of such ingredients or compositions. Antioxidant activity indicates a capability to reduce oxidizing agents (oxidants). This assay quantifies the degree and length of time it takes to inhibit the action of an oxidizing agent, such as oxygen radicals, that are known to cause damage to cells (e.g., skin cells). The ORAC value of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification can be determined by methods known to those of ordinary skill in the art (see U.S. Publication Nos. 2004/0109905 and 2005/0163880; and commercially available kits such as Zen-Bio ORAC Anti-oxidant Assay kit (#AOX-2)). The Zen-Bio ORAC Anti-oxidant Assay kit measures the loss of fluorescein fluorescence over time due to the peroxyl-radical formation by the breakdown of AAPH (2,2′-axobis-2-methyl propanimidamide, dihydrochloride). Trolox, a water soluble vitamin E analog, serves as positive control inhibition fluorescein decay in a dose dependent manner.

Mushroom tyrosinase activity assay: In mammalian cells, tyrosinase catalyzes two steps in the multi-step biosynthesis of melanin pigments from tyrosine (and from the polymerization of dopachrome). Tyrosinase is localized in melanocytes and produces melanin (aromatic quinone compounds) that imparts color to skin, hair, and eyes. Purified mushroom tyrosinase (Sigma) can be incubated with its substrate L-Dopa (Fisher) in the presence or absence of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. Pigment formation can be evaluated by colorimetric plate reading at 490 nm. The percent inhibition of mushroom tyrosinase activity can be calculated compared to non-treated controls to determine the ability of test ingredients or combinations thereof to inhibit the activity of purified enzyme. Test extract inhibition was compared with that of kojic acid (Sigma).

Matrix Metalloproteinase 3 and 9 Enzyme Activity (MMP3; MMP9) Assay: An in vitro matrix metalloprotease (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP3 substrates include collagens, fibronectins, and laminin; while MMP9 substrates include collagen VII, fibronectins and laminin. Using Colorimetric Drug Discovery kits from BioMol International for MMP3 (AK-400) and MMP-9 (AK-410), this assay is designed to measure protease activity of MMPs using a thiopeptide as a chromogenic substrate (Ac-PLG42-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5′-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε=13,600 M-lcm-1 at pH 6.0 and above 7). The active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be assayed.

Matrix Metalloproteinase 1 Enzyme Activity (MMP1) Assay: An in vitro matrix metalloprotease (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP1 substrates include collagen IV. The Molecular Probes Enz/Chek Gelatinase/Collagenase Assay kit (#E12055) utilizes a fluorogenic gelatin substrate to detect MMP1 protease activity. Upon proteolytic cleavage, bright green fluorescence is revealed and may be monitored using a fluorescent microplate reader to measure enzymatic activity.

The Enz/Chek Gelatinase/Collagenase Assay kit (#E12055) from Invitrogen is designed as an in vitro assay to measure MMP1 enzymatic activity. The active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be assayed. The assay relies upon the ability of purified MMP1 enzyme to degrade a fluorogenic gelatin substrate. Once the substrate is specifically cleaved by MMP1 bright green fluorescence is revealed and may be monitored using a fluorescent microplate reader. Test materials are incubated in the presence or absence of the purified enzyme and substrate to determine their protease inhibitor capacity.

Cyclooxygenase (COX) Assay: An in vitro cyclooxygenase-1 and -2 (COX-1, -2) inhibition assay. COX is a bifunctional enzyme exhibiting both cyclooxygenase and peroxidase activities. The cyclooxygenase activity converts arachidonic acid to a hydroperoxy endoperoxide (Prostaglandin G2; PGG2) and the peroxidase component reduces the endoperoxide (Prostaglandin H2; PGH2) to the corresponding alcohol, the precursor of prostaglandins, thromboxanes, and prostacyclins. This COX Inhibitor screening assay measures the peroxidase component of cyclooxygenases. The peroxidase activity is assayed colorimetrically by monitoring the appearance of oxidized N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD). This inhibitor screening assay includes both COX-1 and COX-2 enzymes in order to screen isozyme-specific inhibitors. The Colormetric COX (ovine) Inhibitor screening assay (#760111, Cayman Chemical) can be used to analyze the effects of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification on the activity of purified cyclooxygnase enzyme (COX-1 or COX-2). According to manufacturer instructions, purified enzyme, heme and test extracts can be mixed in assay buffer and incubated with shaking for 15 min at room temperature. Following incubation, arachidonic acid and colorimetric substrate can be added to initiate the reaction. Color progression can be evaluated by colorimetric plate reading at 590 nm. The percent inhibition of COX-1 or COX-2 activity can be calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme.

Lipoxygenase (LO) Assay: An in vitro lipoxygenase (LO) inhibition assay. LOs are non-heme iron-containing dioxygenases that catalyze the addition of molecular oxygen to fatty acids. Linoleate and arachidonate are the main substrates for LOs in plants and animals. Arachadonic acid may then be converted to hydroxyeicosotrienenoic (HETE) acid derivatives, that are subsequently converted to leukotrienes, potent inflammatory mediators. This assay provides an accurate and convenient method for screening lipoxygenase inhibitors by measuring the hydroperoxides generated from the incubation of a lipoxygenase (5-, 12-, or 15-LO) with arachidonic acid. The Colorimetric LO Inhibitor screening kit (#760700, Cayman Chemical) can be used to determine the ability of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification to inhibit enzyme activity. Purified 15-lipoxygenase and test ingredients can be mixed in assay buffer and incubated with shaking for 10 min at room temperature. Following incubation, arachidonic acid can be added to initiate the reaction and the mixtures can be incubated for an additional 10 min at room temperature. Colorimetric substrate can be added to terminate catalysis and color progression can be evaluated by fluorescence plate reading at 490 nm. The percent inhibition of lipoxyganse activity can be calculated compared to non-treated controls to determine the ability of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification to inhibit the activity of purified enzyme.

Elastase Assay: EnzChek® Elastase Assay (Kit #E-12056) from Molecular Probes (Eugene, Oreg. USA) can be used as an in vitro enzyme inhibition assay for measuring inhibition of elastase activity for each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. The EnzChek kit contains soluble bovine neck ligament elastin that can be labeled with dye such that the conjugate's fluorescence can be quenched. The non-fluorescent substrate can be digested by elastase or other proteases to yield highly fluorescent fragments. The resulting increase in fluorescence can be monitored with a fluorescence microplate reader. Digestion products from the elastin substrate have absorption maxima at ˜505 nm and fluorescence emission maxima at ˜515 nm. The peptide, N-methoxysuccinyl-Ala-Ala-Pro-Val-chloromethyl ketone, can be used as a selective, collective inhibitor of elastase when utilizing the EnzChek Elastase Assay Kit for screening for elastase inhibitors.

Oil Control Assay: An assay to measure reduction of sebum secretion from sebaceous glands and/or reduction of sebum production from sebaceous glands can be assayed by using standard techniques known to those having ordinary skill in the art. In one instance, the forehead can be used. Each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be applied to one portion of the forehead once or twice daily for a set period of days (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or more days), while another portion of the forehead is not treated with the composition. After the set period of days expires, then sebum secretion can be assayed by application of fine blotting paper to the treated and untreated forehead skin. This is done by first removing any sebum from the treated and untreated areas with moist and dry cloths. Blotting paper can then be applied to the treated and untreated areas of the forehead, and an elastic band can be placed around the forehead to gently press the blotting paper onto the skin. After 2 hours the blotting papers can be removed, allowed to dry and then transilluminated. Darker blotting paper correlates with more sebum secretion (or lighter blotting paper correlates with reduced sebum secretion.

Erythema Assay: An assay to measure the reduction of skin redness can be evaluated using a Minolta Chromometer. Skin erythema may be induced by applying a 0.2% solution of sodium dodecyl sulfate on the forearm of a subject. The area is protected by an occlusive patch for 24 hrs. After 24 hrs, the patch is removed and the irritation-induced redness can be assessed using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. Immediately after reading, the area is treated with the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. Repeat measurements can be taken at regular intervals to determine the formula's ability to reduce redness and irritation.

Skin Moisture/Hydration Assay: Skin moisture/hydration benefits can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72° C.). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance. Each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be assayed according to this process.

Skin Clarity and Reduction in Freckles and Age Spots Assay: Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a²+b²)^(1/2).

Skin Dryness, Surface Fine Lines, Skin Smoothness, and Skin Tone Assay: Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.

Clinical Grading of Skin Tone Assay: Clinical grading of skin tone can be performed via a ten point analog numerical scale: (10) even skin of uniform, pinkish brown color. No dark, erythremic, or scaly patches upon examination with a hand held magnifying lens. Microtexture of the skin very uniform upon touch; (7) even skin tone observed without magnification. No scaly areas, but slight discolorations either due to pigmentation or erythema. No discolorations more than 1 cm in diameter; (4) both skin discoloration and uneven texture easily noticeable. Slight scaliness. Skin rough to the touch in some areas; and (1) uneven skin coloration and texture. Numerous areas of scaliness and discoloration, either hypopigmented, erythremic or dark spots. Large areas of uneven color more than 1 cm in diameter. Evaluations were made independently by two clinicians and averaged.

Clinical Grading of Skin Smoothness Assay: Clinical grading of skin smoothness can be analyzed via a ten point analog numerical scale: (10) smooth, skin is moist and glistening, no resistance upon dragging finger across surface; (7) somewhat smooth, slight resistance; (4) rough, visibly altered, friction upon rubbing; and (1) rough, flaky, uneven surface. Evaluations were made independently by two clinicians and averaged.

Skin Smoothness and Wrinkle Reduction Assay With Methods Disclosed in Packman et al. (1978): Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman et al. (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.

Skin Firmness Assay with a Hargens Ballistometer: Skin firmness can be measured using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.

Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer: Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).

Appearance of Lines and Wrinkles Assay with Replicas: The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and are of the replicas covered by wrinkles or fine lines was determined.

Surface Contour of the Skin Assay with a Profilometer/Stylus Method: The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: R_(a)=Standardize roughness; l_(m)=the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height (x-axis).

MELANODERM™ Assay: In other non-limiting aspects, the efficacy of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be evaluated by using a skin analog, such as, for example, MELANODERM™. Melanocytes, one of the cells in the skin analog, stain positively when exposed to L-dihydroxyphenyl alanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM™, can be treated with a variety of bases containing each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification or with the base alone as a control. Alternatively, an untreated sample of the skin analog can be used as a control.

Production of Filaggrin: Changes in the production of filaggrin in keratinocytes due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Filaggrin is the precursor to Natural Moisturizing Factor (NMF) in the skin. Increased NMF increases the moisture content of the skin. Filaggrin production in treated and non-treated keratinocytes can be determined using a bioassay that analyzes filaggrin concentration in keratinocyte cell lysates. A non-limiting example of a bioassay that can be used to quantify filaggrin production is the PROTEINSIMPLE® Simon™ western blotting protocol. For each sample, normal human epidermal keratinocytes (NHEK) are grown in EPI-200—Mattek Epilife® growth media with calcium from Life Technologies (M-EP-500-CA). NHEK are incubated in growth medium overnight at 37° C. in 5% CO₂ prior to treatment. NHEK are then incubated in growth medium with 1% test compound/extract or no compound/extract (negative control) for 24 to 36 hours. The NHEK can then be washed, collected, and stored on ice or colder until lysed on ice using a lysis buffer and sonication. The protein concentrations of the samples can be determined and used to normalize the samples. The lysates can be stored at −80° C. until use in the quantification assay.

The PROTEINSIMPLE® Simon™ western blotting bioassay assay employs a quantitative western blotting immunoassay technique using an antibody specific for filaggrin to quantitatively detect filaggrin in the test samples. Cell samples are lysed and normalized for protein concentration. Normalized samples and molecular weight standards can then be loaded and ran on a denatured protein separation gel using capillary electrophoresis. The proteins in the gel are immobilized and immunoprobed using a primary antibody specific for filaggrin. The immobilized proteins can then be immunoprobed with an enzyme-linked detection antibody that binds the primary antibody. A chemiluminescent substrate solution can then be added to the immobilized proteins to allow chemiluminescent development in proportion to the amount of filaggrin bound in the immobilization. The chemiluminescent development is stopped at a specific time and the intensity of the chemiluminescent signal can be measured and compared to positive and negative controls.

Production of Occludin: Changes in the production of occludin in keratinocytes due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Occludin is a protein critical to the formulation of tight junctions and the skin's moisture barrier function. A non-limiting example of how occludin production in treated and non-treated keratinocytes can be determined is by the use of a bioassay that analyzes occludin concentration in keratinocyte cell lysates. The bioassay can be performed using PROTEINSIMPLE® Simon™ western blotting protocol. For the samples, adult human epidermal keratinocytes (HEKa) from Life Technologies (C-005-5C) can be grown at 37° C. and 5% CO2 for 24 hours in Epilife growth media with calcium from Life Technologies (M-EP-500-CA) supplemented with Keratinocyte Growth Supplement (HKGS) from Life Technologies (S-101-5). HEKa are then incubated in growth medium with test compound/extract, no compound/extract for negative control, or with 1 mM CaCl₂ for positive control for 24 to 48 hours. The HEKa are then washed, collected, and stored on ice or colder until lysed on ice using a lysis buffer and sonication. The protein concentrations of the samples can be determined and used to normalize the samples. The lysates are stored at −80° C. until use in the bioassay.

Keratinocyte Monolayer Permeability: Changes in the permeability of a keratinocyte monolayer due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Keratinocyte monolayer permeability is a measure of skin barrier integrity. Keratinocyte monolayer permeability in treated and non-treated keratinocytes can be determined using, as a non-limiting example, the In Vitro Vascular Permeability assay by Millipore (ECM642). This assay analyzes endothelial cell adsorption, transport, and permeability. Briefly, adult human epidermal keratinocytes from Life Technologies (C-005-5C) can be seeded onto a porous collagen-coated membrane within a collection well. The keratinocytes are then incubated for 24 hours at 37° C. and 5% CO₂ in Epilife growth media with calcium from Life Technologies (M-EP-500-CA) supplemented with Keratinocyte Growth Supplement (HKGS) from Life Technologies (S-101-5). This incubation time allows the cells to form a monolayer and occlude the membrane pores. The media is then replaced with fresh media with (test sample) or without (non-treated control) test compounds/extracts and the keratinocytes are incubated for an additional 48 hours at 37° C. and 5% CO₂. To determine permeability of the keratinocyte monolayer after incubation with/without the test compound/extract, the media is replaced with fresh media containing a high molecular weight Fluorescein isothiocyanate (FITC)-Dextran and the keratinocytes are incubated for 4 hours at 37° C. and 5% CO₂. During the 4 hours incubation, FITC can pass through the keratinocytes monolayer and porous membrane into the collection well at a rate proportional to the monolayer's permeability. After the 4 hour incubation, cell viability and the content of FITC in the collection wells can be determined. For the FITC content, the media in the collection well is collected and fluorescence of the media determined at 480 nm (Em) when excited at 520 nm. Percent permeability and percent change in comparison to the non-treated controls can be determined by the following equations: Percent Permeability=((Mean Ex/Em of test sample)/Mean Ex/Em untreated control)*100; Percent Change=Percent Permeability of test sample−Percent Permeability of untreated control.

Production of Hyaluronic Acid: Changes in the production of hyaluronic acid in human dermal fibroblasts due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. HA is a polysaccharide involved in stabilization of the structure of the matrix and is involved in providing turgor pressure to tissue and cells. As one non-limiting example, HA production in treated and non-treated adult human dermal fibroblasts (HDFa) cells can be determined using the Hyaluronan DuoSet ELISA kit from R&D Systems (DY3614). In this assay, for production of samples, subconfluent HDFa cells from Cascade Biologics (C-13-5C) are incubated at 37° C. and 10% CO₂ in starvation medium (0.15% fetal bovine serum and 1% Penicillin Streptomycin solution in Dulbecco's Modified Eagle Medium) for 72 hours prior to treatment. The cells are then incubated with fresh starvation medium with either test compound, positive control (phorbol 12-myristate 13-acetate from Sigma-Aldrich (P1585) and platelet derived growth factor from Sigma-Aldrich (P3201)), or no additive for 24 hours. Media is then collected and frozen at −80° C. until use in the ELISA assay.

Briefly, the ELISA assay employs a quantitative sandwich enzyme immunoassay technique whereby a capture antibody specific for HA can be pre-coated onto a microplate. Standards and media from treated and untreated cells are pipetted into the microplate wells to enable any HA present to be bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked detection antibody specific for HA is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells to allow color development in proportion to the amount of HA bound in the initial step. The color development is stopped at a specific time and the intensity of the color at 450 nm can be measured using a microplate reader.

Inhibition of Hyaluronidase Activity: Changes in the activity of hyaluronidase due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Hyaluronidase is an enzyme that degrades HA. HA is a polysaccharide involved in stabilization of the structure of the matrix and is involved in providing turgor pressure to tissue and cells. As one non-limiting example, hyaluronidase activity can be determined using an in vitro protocol modified from Sigma-Aldrich protocol #EC 3.2.1.35. Briefly, hyaluronidase type 1-S from Sigma-Aldrich (H3506) is added to microplate reaction wells containing test compound or controls. Tannic acid can be used as a positive control inhibitor, no test compound can be added for the control enzyme, and wells with test compound or positive control but without hyaluronidase can be used as a background negative control. The wells are incubated at 37° C. for 10 minutes before addition of substrate (HA). Substrate is added and the reactions incubated at 37° C. for 45 minutes. A portion of each reaction solution is then transferred to and gently mixed in a solution of sodium acetate and acetic acid pH 3.75 to stop that portion of the reaction (stopped wells). The stopped wells and the reaction wells should both contain the same volume of solution after addition of the portion of the reaction solution to the stopped wells. Both the reaction wells and the stopped wells are incubated for 10 minutes at room temperature. Absorbance at 600 nm is then measured for both the reaction wells and the stopped wells. Inhibition can be calculated using the following formulas: Inhibitor (or control) activity=(Inhibitor stopped wells absorbance at 600 nm—inhibitor reaction wells absorbance at 600 nm); Initial activity=control enzyme absorbance at 600 nm; Percent Inhibition=[(Initial activity/Inhibitor Activity)*100]-100.

Peroxisome Proliferator-Activated Receptor Gamma (PPAR-γ) Activity: Changes in the activity of PPAR-γ due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. PPAR-γ is a receptor critical for the production of sebum. As one non-limiting example, the activity of PPAR-γ can be determined using a bioassay that analyzes the ability of a test compound or composition to inhibit binding of a ligand. Briefly, fluorescent small-molecule pan-PPAR ligand, FLUORMONE™ Pan-PPAR Green, available from Life Technologies (PV4894), can be used to determine if test compounds or compositions are able to inhibit binding of the ligand to PPAR-γ. The samples wells include PPAR-γ and fluorescent ligand and either: test compound or composition (test); a reference inhibitor, rosiglitazone (positive control); or no test compound (negative control). The wells are incubated for a set period of time to allow the ligand opportunity to bind the PPAR-γ. The fluorescence polarization of each sample well can then be measured and compared to the negative control well to determine the percentage of inhibition by the test compound or composition.

Cytokine array: Human epidermal keratinocytes are cultured to 70-80% confluency. The media in the plate is aspirated and 0.025% trypsin/EDTA is added. When the cells became rounded, the culture dish is gently tapped to release the cells. The trypsin/EDTA containing cells are removed from the culture dish and neutralized. Cells are centrifuged for 5 min. at 180×g to form a pellet of cells. The supernatant is aspirated. The resulting pellet is resuspended in EpiLife™ media (Cascade Biologics). The cells are seeded in 6-well plates at approximately 10-20% confluency. After the cells became approximately 80% confluent, the media is aspirated and 1.0 ml of EpiLife™, along with phorbol 13-Myristate 12-acetate (“PMA”) (a known inducer of inflammation) and the test composition dilutions are added to two replicate wells (i.e., 1.0% (100 μl of 100× stock) and 0.1% (10 μl of 100× stock) test compositions are diluted into a final volume of 1 ml EpiLife Growth Medium). The media is gently swirled to ensure adequate mixing. In addition, 1.0 ml of EpiLife™ is added to the control wells, with and without additional PMA. The plates are then incubated at 37±1° C. and 5.0±1% CO₂ for approximately 5 hours after dosing. Following this 5-hour incubation, all media is collected in conical tubes and frozen at −70° C.

For analysis, a 16-pad hybridization chamber is attached to 16-pad FAST slides arrayed in triplicate with 16 anti-cytokine antibodies plus experimental controls (Whatman BioSciences), and the slides are placed into a FASTFrame (4 slides per frame) for processing. Arrays are blocked for 15 min. at room temp. using 70 ml S&S Protein Array Blocking buffer (Whatman Schleicher and Scheull). Blocking buffer is removed and 70 ml of each supernatant sample is added to each array. Arrays are incubated for 3 hours at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T. Arrays are treated with 70 ml of an antibody cocktail, containing one biotinylated antibody corresponding to each of the arrayed capture antibodies. Arrays are incubated for 1 hour at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T. Arrays are incubated with 70 ml of a solution containing streptavidin-Cy5 conjugate for 1 hour at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T, quickly rinsed in de-ionized water, and dried.

Slides can be imaged in a Perkin-Elmer ScanArray 4000 confocal fluorescent imaging system. Array images can be saved and analyzed using Imaging Research ArrayVision software. Briefly, spot intensities are determined by subtracting background signal. Spot replicates from each sample condition can be averaged and then compared to the appropriate controls.

Endothelial Tube Formation: Endothelial tube formation is involved in angiogenesis and micro-vessel capillary formation. Capillary formation and angiogenesis may contribute to redness and rosacea of the skin. The ability for endothelial cells to form tubes in the presence or absence of test extracts and compounds may be determined using a capillary tubule disruption assay with pre-formed primary human umbilical vein endothelial cells (HUVEC) in a cell culture system.

Briefly, HUVECs are cultured in vitro on Extracellular Matrix, which stimulates the attachment and tubular morphogenesis of endothelial cells to form capillary-like lumen structures. These in vitro formed capillary tubules are similar to human blood vessel capillaries in many aspects. The capillary tube assay is based on this phenomenon and is used for evaluation of potential vasculature targeting agents.

HUVEC cultures are grown in a 5% CO₂ 37° C. cell incubator. The full growth medium for HUVECs is Endothelial Cell Basal Medium (EBM) supplemented with 2% fetal bovine serum (FBS), 12 μg/ml bovine brain extract, 1 μg/ml hydrocortisone, and 1 μg/ml GA-1000 (gentamicin-amphothericin). HUVEC cultures between passage 3 and 8 may be used for all assay experiments.

HUVECs are pre-labeled with fluorescent agent Calcein AM and seeded in Extracellular Matrix coated 96-well culture plate with their full growth medium. After about four hours of the morphogenesis process, the endothelial capillary tubes should be formed. Then, test agent in designed doses in 50 μl volume is applied into the formed capillary tubule cultures as treatment conditions. The no-treatment controls can be added with vehicle of test agents. Sutent, a FDA approved anti-angiogenic drug one concentration can be included as assay performance control. After about six hours of treatment, the endothelial tubule morphology in each well is examined by microscopy, imaged, and the capillary disrupting activities under treatment conditions can be quantitatively analyzed. Each test conditions can be conducted in duplicate wells, including controls.
